Welcome to Geolexica, the authoritative glossary for geographic information technology from ISO/TC 211.

The name “geolexica” is the combination of the Greek prefix “geo-” (of and pertaining to the Earth) and the suffix “lexica” derived from Greek “lexiko”, the counterpart of English “lexicon” (vocabulary).

Terms on this site are managed by the ISO/TC 211 Terminology Management Group (TMG). The Chair of the TMG is Reese Plews.
